Oil RecommendationsUsing the proper type and weight of oil in thecrankcase is extremely important. So is checking oildaily and changing oil regularly. Failure to use thecorrect oil, or using dirty oil, causes premature enginewear and failure.

Oil TypeUse high quality detergent oil of API (AmericanPetroleum Institute) service class SG, SH, SJ or higher.Select the viscosity based on the air temperature at thetime of operation as shown in the following table.

Figure 1. Typical Courage® and Courage PRO™ Series Vertical Shaft Engines.

NOTE: Synthetic oils meeting the listed classificationsmay be used with oil changes performed atthe recommended intervals. However to allowpiston rings to properly seat, a new or rebuiltengine should be operated for at least 50 hoursusing standard petroleum based oil beforeswitching to synthetic oil.

A logo or symbol on oil containers identifies the APIservice class and SAE viscosity grade. See Figure 3.

*Use of synthetic oil having 5W-20 or 5W-30 rating is acceptable,up to 4°C (40°F).

**Synthetic oils will provide better starting in extreme cold below23°C (-10°F).

**

Figure 2. Viscosity Grades Table.

NOTE: Using other than service class SG, SH, SJ orhigher oil or extending oil change intervalslonger than recommended can cause enginedamage.

Fuel Recommendations

WARNING: Explosive Fuel!Gasoline is extremely flammable and its vapors can explode ifignited. Store gasoline only in approved containers, in wellventilated, unoccupied buildings, away from sparks or flames.Do not fill the fuel tank while the engine is hot or running,since spilled fuel could ignite if it comes in contact with hot partsor sparks from ignition. Do not start the engine near spilled fuel.Never use gasoline as a cleaning agent.

General RecommendationsPurchase gasoline in small quantities and store inclean, approved containers. A container with acapacity of 2 gallons or less with a pouring spout isrecommended. Such a container is easier to handle andhelps eliminate spillage during refueling.

Do not use gasoline left over from the previous season,to minimize gum deposits in your fuel system and toensure easy starting.

Do not add oil to the gasoline.

Do not overfill the fuel tank. Leave room for the fuel toexpand.

Fuel TypeFor best results use only clean, fresh, unleaded gasolinewith the pump sticker octane rating of 87 or higher. Incountries using the Research method, it should be 90octane minimum.

Unleaded gasoline is recommended as it leaves lesscombustion chamber deposits and reduces harmfulexhaust emissions. Leaded gasoline is notrecommended.

Gasoline/Alcohol blendsGasohol (up to 10% ethyl alcohol, 90% unleadedgasoline by volume) is approved as a fuel for Kohlerengines. Other gasoline/alcohol blends including E20and E85 are not to be used and not approved. Anyfailures resulting from use of these fuels will not bewarranted.

Gasoline/Ether blendsMethyl Tertiary Butyl Ether (MTBE) and unleadedgasoline blends (up to a maximum of 15% MTBE byvolume) are approved as a fuel for Kohler engine.Other gasoline/ether blends are not approved.

Engine Identification NumbersWhen ordering parts, or in any communicationinvolving an engine, always give the Model,Specification, and Serial Numbers of the engine.

Pre-Start Checklist• Check oil level. Add oil if low. Do not overfill.

• Check fuel level. Add fuel if low.

• Check cooling air intake areas and externalsurfaces of engine. Make sure they are clean andunobstructed.

• Check that the air cleaner components and allshrouds, equipment covers, and guards are inplace and securely fastened.

• Check that any clutches or transmissions aredisengaged or placed in neutral. This is especiallyimportant on equipment with hydrostatic drive.The shift lever must be exactly in neutral toprevent resistance which could keep the enginefrom starting.

WARNING: Lethal Exhaust Gases!Engine exhaust gases contain poisonous carbon monoxide.Carbon monoxide is odorless, colorless, and can cause death ifinhaled. Avoid inhaling exhaust fumes, and never run theengine in a closed building or confined area.

Cold Weather Starting Hints1. Be sure to use the proper oil for the temperature

expected. See Figure 2 on page 4.

2. Declutch all possible external loads.

3. Be sure the battery is in good condition. A warmbattery has much more starting capacity than acold battery.

4. Use fresh winter grade fuel. NOTE: Winter gradegasoline has higher volatility to improvestarting. Do not use gasoline left over fromsummer.

Starting1. Place the throttle control midway between the

slow and fast positions. Place the choke controlinto the on position.

2. Start the engine by activating the key switch.Release the switch as soon as the engine starts.

NOTE: Do not crank the engine continuously formore than 10 seconds at a time. If the enginedoes not start, allow a 60 second cool downperiod between starting attempts. Failure tofollow these guidelines can burn out thestarter motor.

NOTE: If the engine develops sufficient speed todisengage the starter but does not keeprunning (a false start), engine rotation must

be allowed to come to a complete stop beforeattempting to restart the engine.

If the starter is engaged while the flywheel is rotating,the starter pinion and flywheel ring gear may clash,resulting in damage to the starter.

If the starter does not turn the engine over, shut offstarter immediately. Do not make further attempts tostart the engine until the condition is corrected. Do notjump start using another battery (refer to Battery).See your Kohler Engine Service Dealer for serviceassistance.

3. For a Cold Engine – Gradually return the chokecontrol to the off position after the engine startsand warms up.

The engine/equipment may be operated duringthe warm-up period, but it may be necessary toleave the choke partially on until the enginewarms up.

4. For a Warm Engine – Return choke to off positionas soon as engine starts.

Stopping1. Remove the load by disengaging all PTO driven

attachments.

2. For Engines without a Shutdown Solenoid:Move the throttle to the slow or low idle position.Allow the engine to run at idle for 30-60 seconds;then stop the engine.

For Engines Equipped with a ShutdownSolenoid: Position the throttle control betweenhalf and full throttle; then stop the engine.

BatteryA 12 volt battery is normally used. Refer to theoperating instructions of the equipment this enginepowers for specific battery requirements.

If the battery charge is not sufficient to crank theengine, recharge the battery.

Operating

Angle of OperationThis engine will operate continuously at angles up to25°. Check oil level to assure crankcase oil level is atthe FULL or “F” mark on the dipstick.

Refer to the operating instructions of the equipmentthis engine powers. Because of equipment design orapplication, there may be more stringent restrictionsregarding the angle of operation.

7

NOTE: Do not operate this engine continuously atangles exceeding 25° in any direction. Enginedamage could result from insufficientlubrication.

CoolingNOTE: If debris builds up on the grass screen or other

cooling areas, stop the engine immediatelyand clean. Operating the engine with blockedor dirty air intake and cooling areas can causeextensive damage due to overheating. SeeClean Air Intake/Cooling Area.

Engine SpeedNOTE: Do not tamper with the governor setting to

increase the maximum engine speed.Overspeed is hazardous and will void theengine warranty. The maximum allowablehigh idle speed for these engines is 3675 RPM,no load.

Maintenance InstructionsMaintenance, repair, or replacement of the emission control devices and systems, which are being done at thecustomers expense, may be performed by any non-road engine repair establishment or individual. Warrantyrepairs must be performed by an authorized Kohler service outlet.

WARNING: Accidental Starts!Disabling engine. Accidental starting can cause severe injury or death. Before working on the engine orequipment, disable the engine as follows: 1) Disconnect the spark plug lead(s). 2) Disconnect negative (-) batterycable from battery.

Maintenance ScheduleThese required maintenance procedures should be performed at the frequency stated in the table. They shouldalso be included as part of any seasonal tune-up.

NOTE: Operating the engine with a blocked grassscreen, dirty or plugged cooling fins, and/orcooling shrouds removed, will cause enginedamage due to overheating.

Ignition SystemThese engines use an electronic Capacitive Discharge(CD) ignition system. Other than periodicallychecking/replacing the spark plugs, no maintenance,timing, or adjustments are necessary or possible withthis system.

Check Spark PlugsEvery 100 hours of operation, remove the spark plugs,check condition, and reset the gap or replace with newplugs as necessary. The standard Courage spark plugis a Champion® RC12YC (Kohler Part No. 12 132 02-S).RFI compliant engines use a Champion® XC12YC(Kohler Part No. 25 132 14-S) spark plug. A high-performance spark plug, Champion® Platinum 3071(Kohler Part No. 25 132 12-S) is standard on CouragePRO

™ models. Equivalent alternate brand plugs can

also be used.

1. Before removing the spark plug, clean the areaaround the base of the plug to keep dirt anddebris out of the engine.

2. Remove the plug and check its condition. Replacethe plug if worn or reuse is questionable.

NOTE: Do not clean the spark plug in a machineusing abrasive grit. Some grit could remainin the spark plug and enter the enginecausing extensive wear and damage.

3. Check the gap using a wire feeler gauge. Adjustthe gap to 0.76 mm (0.030 in.) by carefullybending the ground electrode. See Figure 13.

4. Reinstall the spark plug into the cylinder head.Torque the spark plug to 24.4-29.8 N·m(18-22 ft. lb.).

Figure 13. Servicing Spark Plug.

Battery Charging

WARNING: Explosive Gas!Batteries produce explosive hydrogen gas while being charged.To prevent a fire or explosion, charge batteries only in wellventilated areas. Keep sparks, open flames, and other sources ofignition away from the battery at all times. Keep batteries out ofthe reach of children. Remove all jewelry when servicingbatteries.

Before disconnecting the negative (-) ground cable, make sureall switches are OFF. If ON, a spark will occur at the groundcable terminal which could cause an explosion if hydrogen gasor gasoline vapors are present.

Fuel System

Fuel FilterSome engines are equipped with an in-line fuel filter.Periodically inspect the filter and replace with agenuine Kohler filter every 100 operating hours.

Fuel LineIn compliance with CARB Tier III EmissionRegulations, these engines use Low Permeation SAE30 R7 rated fuel line; certified to meet CARBrequirements. Standard fuel line may not be used.Order replacement hose by part number through aKohler Engine Service Dealer.

Figure 14. Low Permeation Fuel Line.

Carburetor Troubleshooting andAdjustmentsIn compliance with government emission standards,the carburetor is calibrated to deliver the correct fuel-to-air mixture to the engine under all operatingconditions. The high speed mixture is set at thefactory and cannot be adjusted. The low idle fueladjustment screw (if equipped) is also set at thefactory and normally does not require adjustment. SeeFigure 15. Engines in this series depending on themodel and application, may also be equipped with aGoverned Idle System.

If the engine is equipped with a Governed Idle System,refer to Models with Governed Idle System whenperforming any carburetor adjustment, as anadditional step to the listed procedure(s) is required.

If, after checking the items listed above, the engine ishard to start, runs roughly, or stalls at low idle speed,it may be necessary to adjust or service the carburetor.

Adjust CarburetorNOTE: Some engines may have a fixed (capped) idle

fuel adjusting screw or limiter cap. On theseengines, do not attempt steps 1 and 2 below.Proceed directly to Step 3. On limiterequipped models, adjustment can only beperformed within the limits allowed by thecap.

1. Idle Fuel Adjustment: with the engine stopped,turn the low idle fuel adjusting screw in(clockwise) until it bottoms lightly. See Figures 15and 16.

NOTE: The tip of the low idle fuel adjusting screw istapered to critical dimensions. Damage to theneedle tip and the seat in carburetor bodywill result if the needle is forced.

2. Preliminary Settings: Turn the adjusting screwout (counterclockwise) from lightly bottomed2-1/4 turns.

3. Start the engine and run at half throttle for 5 to 10minutes to warm up. The engine must be warmbefore making final settings (steps 4, 5, and 6).

4. Low Idle Speed (RPM) Setting: Place the throttlecontrol into the idle or slow position. Set the lowidle speed to 1200 RPM* (± 75 RPM) by turning thelow idle speed adjusting screw in or out. Checkthe speed using a tachometer.

*NOTE: The actual low idle speed depends on theapplication – refer to equipmentmanufacturer’s recommendations. Therecommended low idle speed for basic enginesis 1200 RPM. To ensure best results whensetting the low idle fuel needle, the low idlespeed must not exceed 1200 RPM(± 75 RPM).

5. If proper operation is not restored after adjusting,carburetor servicing by an authorized KohlerEngine Service Dealer may be required.

Models with Governed Idle SystemAn optional governed idle control system is suppliedon some engines. The purpose of this system is tomaintain a desired idle speed regardless of ambientconditions (temperature, parasitic load, etc.) that maychange. Engines with this feature contain a smallsecondary spring connected between the governorlever and the lower adjustment tab of the mainbracket. See Figure 17.

Figure 16. Carburetor Adjustment Access Locations(Latch Removed For Clarity).

TroubleshootingIf engine troubles are experienced that appear to befuel system related, check the following areas beforeadjusting the carburetor.

• Make sure the fuel tank is filled with clean, freshgasoline.

• Make sure the fuel tank cap vent is not blockedand that it is operating properly.

• If the fuel tank is equipped with a shut-off valve,make sure it is open.

• If the engine is equipped with an in-line fuel filter,make sure it is clean and unobstructed. Replacethe filter if necessary.

• Make sure fuel is reaching the carburetor. Thisincludes checking the fuel lines and fuel pump forrestrictions or faulty components, replace asnecessary.

• Make sure the air cleaner element is clean and allair cleaner element components are fastenedsecurely.

The system requires an additional procedure forsetting the idle speed. If speed adjustments arerequired proceed as follows.

1. Make any necessary speed or control adjustmentsfollowing the appropriate instructions covered inthis section.

2. Move the throttle control to the idle position. Holdthe governor lever away from the carburetor, orhold the throttle lever so it is tight against the idlespeed adjusting screw, to negate the governoractivation. See Figure 18. Check the speed with atachometer and adjust it to 1500 RPM.

3. Release the governor lever and allow the engine toreturn to the governed idle speed. Check it with atachometer against the equipment manufacturersrecommended idle speed. Governed Idle Speed(RPM) is typically 300 RPM (approximate) higherthan the low idle speed. If adjustment isnecessary, bend the adjusting tab on the speedcontrol assembly to set. See Figure 17.
